WHAT REALLY HAPPENED ON THE BLACK MESA AND LAKE POWELL?

In the face of conflicting reports concerning the track problems of the Black Mesa & Lake Powell, this article reports the results of an on-site investigation. Management view is that the track bed is sound, rail was properly laid and has perfact alignment, but there have been problems with rail fastenings. This has led to problems with the concrete cross ties, which developed spalling under the rails. BM&LP is replacing about 75,000 of its original 196,000 concrete ties with 100,000 wood ties, leaving 121,000 concrete ties in service. All concrete ties on curves greater than 30 minutes are being replaced. The spalled areas of all remaining ties are being repaired with a sand/epoxy mix. Clip bolts on all remaining concrete ties are being replaced with high-tensile steel and the rubber pads under the rails are being replaced with hard polyethylene pads, retaining original clips.
